The current release of OpenBSD is 4.3 (fourthree) “which was released May 1, 2008″. My desktop, an old pentium IV, gives me a higher security level when I’m outside… It, from here just called lesbian (’cause my machine love girls too), was running OpenBSD 4.2 (release) and worked fine. Since I use subversion (thanks to Razzolini) and my tree (.confs, scripts, rcs, etc) is always up-to-date, I didn’t care about its installation. I re-installed OpenBSD and got everything working again until May 1 (due to “hours fuse issues”).

I had time to download sUxbuntu 8.04 and after some time nothing happened: the motherfuckingfocker ubiquity installer crashes if I try to do a manual partitioning. Then I downloaded Kubuntu 8.04: it installs and works (points to Kubuntu’s team!!!) quite fine. I’ve decided to abandon *buntu family.

My OpenSolaris is working great and I approve (give it a try! ; ).

M$ Windows 2008 Enterprise Edition (just for eval, 60 days) is working fine too…

O Ubuntu funciona e isto nao e’ nenhuma grande novidade… Removi duas maquinas virtuais que nao estavam em uso, e re-instalei o ubuntu (feisty amd64, que nao apresenta problemas na instalacao, depois fiz o upgrade pro gutsy via do-release-upgrade). Enfim: tudo funcionando lindamente, tudo bem bonito. E seguindo a “filosofia ubuntu”: enviadei o desktop, deixando um papel de parede maygo, icones felizes, um cursor pra la’ de saltitante e um terminalzinho com “true transparency”, ui! Faltam algumas coisas fofas, mas isso vem com o tempo, certo? Algo que me irritava era as unidades montadas aparecendo no desktop. Depois de conversar com Deus, encontrei no forum feliz do Ubuntu como esconder os icones:

gconftool-2 --type boolean --set /apps/nautilus/desktop/volumes_visible false

E nao e’ que funcionou?!

Bem, existem algumas coisas na agulha, e quero ver se coloco o quanto antes aqui:

* netsed - on-the-fly packet modifier; brincadeiras simples e infantis…

* samba3 - vfs modules; alguns truques legais, como auditoria, lixeira, etc, e como hackear o samba, adicionando debugs nos lugares certos

* fbmyip - from beyond my ip; servico simples, em ruby, que faz quase o que o no-ip.org faz, escrito em ruby (e rails)

* freedns.afraid.org - dica legal de dns dinamico, bem completo.

* mysql: replication, failover, load balance :S

You can speed up your vm`s in VMware Server Console by defrag*** a virtual disk. After you got your vm running as fastest as it can, just click on VM Settings and then select Hard Disk; so, click on “Defragment” button, and wait some seconds (or minutes/hours/days… i`m just kidding).

After, the machine taked up 1min to boot. Now, it takes almost one minute, but suspend/resume time decreased from one minute to few seconds.

Please, read:

* you can’t do that if your machine is suspended, so you need to poweroff

* it won’t do any effect if you have pre-allocated the disk (works only with virtual disks, not plain or physical disks, as described here).

ps: defrag means to me the oldest procedure on win9x (scandisk, defrag, etc), when life was not too good

After many headaches, I’ve installed Ubuntu Gutsy Gibbon 32 bits on my little desktop (Lenovo 3000 N100 0768DKU which supposed to be x86_64; the fact that it is, but Ubuntu amd64′ install is VERY LAME, and crashes at 15% of filesystem detections), and here is my desktop, working fine and beauty.

ps: it was made using recordmydesktop and mencoder, to convert ogg to avi.

Instalar o Rails no Gibão (ao jeito Ubuntu de viver) é algo realmente simples. Não recomendo instalar o rails que está disponível no apt.

apt-get install ruby-full rubygems

gem install rails –include-dependencies -y

E em 15mins tudo pronto Simples assim
